To Be Promised: Psycho Lesbian Sister's Sadistic Obsession

Olive Glass is beautiful, the kind of beauty men pay to touch and forget to hate themselves for it. Tonight she is on her knees, collared, quiet, waiting for orders. Derrick holds the chain, but he is not the only one who thinks the girl belongs to him. Years ago she made a promise to her step-sister Alex, a hungry promise whispered against a shower wall while Alex fingered her open. Olive said if you’ll take my cunt I’ll give you everything. Alex never let that vow die. Alex shows up, clears the men out, and takes what is hers. Derrick answers by locking Olive in hard leather cuffs, cane in one hand, candle in the other. Hot wax stripes across her tits, clamps bite her nipples, the flogger lands until her skin burns red. She moans through it all, promises she will wear his collar forever if he will only let her come. When he slides his cock inside her, she rides like a woman trying to outrun her past. He fucks her deep and slow, grants her orgasm only after she promises to break the news to Alex herself. Olive walks into the kitchen trembling, collar gleaming, voice small. Alex sees it and the calm leaves her face. She grabs her sister, spins her, slaps her ass until it glows. She stuffs an electric plug into Olive’s cunt, cuffs her wrists behind her back, turns the audio setting high, and sits on her mouth. Every moan Alex makes shocks the electrodes. Olive squeals, hips jerking, cunt clenching around the current while Alex comes loud and vicious on her tongue. Derrick finds them like that and smiles. He drags Alex to the floor, ropes her wrists, ankles, spreads her open. He crops her, spanks her, then drives his cock straight into her ass. Alex arches, curses, laughs, taking every thrust while Olive struggles free in the hallway. When Olive finally stumbles in, Derrick is deep in Alex’s throat. He pulls out long enough to tell Olive to sit on her sister’s face. Olive obeys. The three of them tangle until the only sounds left are skin slapping skin, Alex gasping, Olive licking thick white cum from Alex’s swollen cunt.
